One of the history code was set in the last 3 ignition cycles and it is likely an emission related code that turned on the light. The light will go out after 3 ignition cycles if the fault is not detected again. Clearing the codes will also clear the historical codes.

Ranger is exactly right. Clear the codes and see which come back.

By the time you stop the car and check the codes it goes into history.

The Sticky at the the top has the link if you want to Clear Codes. Or you can run the Codes before you shut it off.
